. Therefore, we intend to implement richer cost-based optimization in the future. The physical plan also performs rule-based physical optimizations, such as merging pipeline projects or filters into one spark map operation. In addition, it can push operations from a logical plan to a data source that supports predicates or projects pushed down. We will describe the APIs for these data sources in a later section. In general, the physical plan rules have approximately 500 lines of code.code Genera

-completion (ie acp , omnicppcompleter ), code checking () and Syntastic so on.There are two main implementations of this function for text auto-completion . Based on text What we often use, the omnicppcompleter acp way vim comes into being, c-x, c-n is based on text. A more popular statement is actually a word: guessIt uses text to make some regular expression matching, and then according to the generated tags (using the ctags build) to achieve the effect of auto-completion.

I have been searching for a useful JavaScript Parser for Jscex. Previously I used Narcissus and wrote related articles. Unfortunately, Narcissus uses the extension of SpiderMonkey, so it is not implemented using ECMAScript 3 and cannot be used in IE 8 or other browsers. Currently, Jscex uses the earlier version of Narcissus in NarrativeJS, but I do not like the AST structure output. I also found some bugs in advanced functions, which may seem boring,
